do this analysis, we perform it in the molecular genetic laboratory at the republican scientific and practical center of onologyatives and invite them for a detailed examination, if they are also confirmed to be carriers of this gene , depending on its structure, specifically the structure of this gene, because there are different types of genotype, we offer either dynamic observation or surgical intervention, now preventive such operations, specifically for hereditary forms of cancer, we performed 20 operations, 10 of them on children. and now ten children, our youngest girl was 4 years old, the oldest boy was 15, 15 years old, out of ten children, two were confirmed to have cancer, that is, well, i’m an oncologist, i can’t say at stage zero, but at initial stage, but in adults the situation is worse, in adults, out of ten adults, eight were confirmed to have cancer, two a precancerous tumor, so the technique works, it is quite unique for us, in the west it already works. there is the concept of the first, second, third, fourth stages, and the development of cancer, is it possible to talk about the zero stage
